C++ help

only use the cin and cout object in the main function of your program. You must also create at least one other function outside of main. Write a program that determines the day of the week for a given date. You can invent your own complex algorithm that takes into account the special leap year rules, and changes in calendars, but this is a case where it makes sense to look for things that are familiar. you will find that there is a standard way or representing a date, called the Julian Day Number (JDN). This is the number of days that have elapsed since January 1, 4713 BC. Given the JDN for a date, there is a simple formula that tells the day of the week: DayofWeek = (JDN + 1) % 7 The result is in the range of 0 to 6, with 0 representing Sunday. The only remaining problem is how to compute the JDN, which is not so simple. The algorithm computes several intermediate results that are added together to give the JDN. We look at the computation of each of these three intermediate values in turn. If the date comes from the Gregorian calendar (later than October 15, 1582), then compute intRes1 with the following formula, otherwise let intRes1 be zero. intRes1 = 2 ??" year / 100 + year / 400 (integer division) The second intermediate result is computed as follows: intRes2 = int(365.25 * year) We compute the third intermediate value with this formula: intRes3 = int(30.6001 * (month + 1) ) Finally, the JDN is computed this way: JDN = intRes1 + intRes2 + intRes3 + day + 1720994.5 Your program should make appropriate use of value-returning functions in solving this program. These formulas require nine significant digits; you may have to use the integer type long and the floating-point type double. Your program should prompt appropriately for input of the date, and properly label the output. Use proper coding style with comments to document the algorithm as needed. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
